METHOD FOR MANUFACTURE OF SILICONE CASINGS FOR LOWER LIMB STUMPS Russian patent published in 2001 - IPC

Abstract RU 2166302 C2

FIELD: medical equipment, in particular, prosthetics. SUBSTANCE: first version of method involves forming contact-supporting member from silicone composition; heating form to 80 C plus and minus 10 C in case dipping method is employed; dipping form into prepared silicone composition vacuumized to complete removal of air bubbles and holding for 3- 9 min depending upon size and thickness of casing; quickly withdrawing form with casing from composition and putting it for curing at temperature of 100 C plus and minus 5 C for 20 min. Second version of method for manufacture of reinforced casing involves heating form to temperature of 70 C plus and minus 5 C and putting reinforcing woven casing on it; dipping it together with form into prepared silicone composition and holding in it for 5-11 min depending upon size and thickness of casing proximal part; withdrawing form from composition and putting for curing at temperature of 100 C plus and minus 5 C for 20 min. EFFECT: increased efficiency and simplified method for manufacture of supporting and reinforced casings for lower limb stumps from silicone. 3 cl, 7 dwg
